I had a vacuum assisted birth 12/16 and my sons head is still a little long looking from the side. Some said 6 weeks is when they’re head gets more roundish but we’re hitting 6 weeks next week and I see no change. It’s only noticeable from the side. How long does it take to fully round out. My pediatrician said nothing about it besides one side is a little bigger but she said it’s normal with a vacuum birth. I’m just wondering if he’ll need a helmet or something or simply time.
